there's a lot to be done in security with such a big airport like dallas, for instance. let me go back to the dogs here. my understanding of the dollars and the metrics here, and again, if we can't correct the record here as a follow-up, my understanding is it costs roughly about $175,000 per whole body imaging machine, but the dogs are like $20,000-$3,000 to have a dog ready to go. i'm pretty sure those are the records, but to the point, the whole body imaging machines have something the dogs don't have. they is lobbyists. what's infearuating is the challenge is we have to increase the security. we have to become more secure. we can't give up every civil liberty and looking at every passenger naked in order to secure the airport. we need good dogs. the pentagon spending $19 billion came to the conclusion as i pointed out with the lieutenant colonels comments, the best way to find a bomb making device or materials is the canine. there's not enough emphasis on expending the use of dogs. they are friendly, noninvasive, effective, they are the single best weapon according t
